Questione giuridica chiave
Whether the appeal was filed in time despite unclear proof of service of the cantonal decision.
Decisione estratta
The filing was treated as timely because the date of service was not documented and the appellant's statement that he received the decision on 2010-09-22 was accepted.
Motivazione estratta
The burden of proving service lies with the authority file; without proof, the court relied on the appellant's account and deemed both submissions timely under Art. 100(1) BGG.
